libvm-ec2-security-credentialcache-perl 0.23-1 (amd64 binary) in ubuntu xenial

 VM::EC2::Security::CredentialCache provides a cache for an EC2's IAM
 credentials represented by VM::EC2::Security::Credentials. Rather than
 retriving the credentials for every possible call that uses them, cache them
 until they expire and retrieve them again if they have expired.
